Déployer l'industrie 5.0 pour les systèmes de production circulaires : une approche systémique et centrée sur l'humain
No full textThis thesis explores the integration of Industry 5.0 digital technologies (DT) into circular manufacturing systems (CMS) through four main phases. First, literature reviews and a survey on professional industrialists were conducted to identify the levers and barriers of DT and CMS, as well as the potential synergies between this industrial production system and emerging technologies. The results revealed a lack of empirical evidence and contradictions between the literature in the humanities and social sciences (H&SS) and engineering. Second, a discrete event simulation was developed based on observations of an industrial field and experiments in a training factory. This simulation integrates the inter-individual variabilities of operators, their health and a circular learning process, to personalize training paths. Third, a workstation analysis allowed the selection of the cobot as the technology of interest for a disassembly station. The results showed improvement in learning, a reduction of negative biomechanical impacts and a preservation of the operational performance of operators. Finally, a systemic and multidisciplinary methodology was proposed to analyze a CMS and implement TD. It assesses the company's needs and uses sustainability indicators to improve workshop tasks and select appropriate technologies. This thesis combines engineering and H&SS approaches, offering significant contributions to design CMS and providing practical tools for future research.Cette thèse explore l'intégration des technologies digitales (TD) de l'industrie 5.0 dans les systèmes de production circulaire (SPC) à travers quatre phases principales. Premièrement, des revues de littérature et une enquête auprès d'industriels ont été réalisées pour identifier les leviers et barrières des TD et SPC, ainsi que les synergies potentielles entre ce processus de production et les technologies émergentes. Les résultats ont révélé un manque de preuves empiriques et des contradictions entre les littératures en sciences humaines et sociales (SHS) et en ingénierie. Deuxièmement, une simulation d'événements discrets a été développée à partir d'observations d'un terrain industriel et d'expérimentations dans une usine école. Cette simulation intègre les variabilités interindividuelles des opérateurs, leur santé et un processus d'apprentissage circulaire, avec pour objectif de personnaliser les parcours de formation. Troisièmement, une analyse des postes de travail a permis de sélectionner le cobot comme technologie d'intérêt pour un poste de démontage. Les résultats ont montré une amélioration de l'apprentissage, une réduction des impacts biomécaniques négatifs et une préservation de la performance opérationnelle des opérateurs. Enfin, une méthodologie systémique et multidisciplinaire a été proposée pour analyser un SPC et implémenter des TD. Elle évalue les besoins de l'entreprise et utilise des indicateurs de durabilité pour améliorer les tâches de l'atelier et sélectionner les technologies appropriées. Cette thèse combine des approches d'ingénierie et de SHS, offrant des contributions significatives pour les systèmes de production circulaire et fournissant des outils pratiques pour la recherche future
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
